Data Center Real Estate, Measured in Megawatts
Power, not square footage, now sets the value of land and buildings that can support digital infrastructure.
Data center real estate has moved from a niche specialty to a sector that institutional investors, cloud providers, and developers pursue directly. Cloud computing, artificial intelligence, and enterprise networks all depend on facilities that keep servers powered, cooled, and connected.
For most of commercial real estate history, value was measured in square feet. In data center real estate, it is measured in megawatts as much as square feet. The question is no longer only where a building sits, but how much electricity can reach it, and how soon.
That shift reaches Florida owners directly. Some vacant land and some older industrial buildings are worth more to a data center user than to any conventional buyer. Yet apparent power and confirmed power are not the same, and this article explains what owners should establish before testing that value.
Power, the Constraint for Data Center Real Estate
Data centers draw electricity continuously and at a scale few property types approach. U.S. data centers used about 4.4% of the nation's electricity in 2023, and a Department of Energy-sponsored study projects 6.7% to 12% by 2028.
Utilities cannot add that capacity overnight. New substations, transmission lines, and generation take years to plan, permit, and build, and large requests now wait in queues behind other users.
As a result, available power has become the controlling factor in site selection. A parcel or building that can deliver power on a defined timeline offers something capital alone cannot quickly buy: speed to market.
Florida Sets the Terms for Large Loads
Florida has now written those economics into law. SB 484, signed May 7, 2026, requires large users such as hyperscale data centers to pay their full cost of electric service, preserves local governments' authority to reject projects, and creates a dedicated permitting process.
Florida Power & Light, which serves most of South Florida, told regulators in October 2026 that its existing rate structure already complies. Under those terms, data center applicants fund engineering studies, pay up front for new facilities, build their own substations, and sign 20-year minimum contracts.
For owners, the implication is practical. New large-load service is costly and slow to secure, which can favor sites and buildings where capacity is confirmed sooner.
Powered Land, Room to Build
Powered land is vacant acreage with secured or near-term access to the electrical capacity, fiber connectivity, and water that data centers require. It appeals most to hyperscale cloud providers and developers planning large campuses, where scale matters as much as timing.
Value in powered land comes from power and entitlements rather than construction. A site with a signed utility commitment, appropriate zoning, and a clear energization schedule can be worth far more than comparable land without them. That difference is built through studies, agreements, and approvals, the core of Mundial Capital's Development Sites practice and the commercial land expertise behind it.
Size and configuration also matter. Larger users look for contiguous acreage that can hold multiple buildings, an on-site or nearby substation, generator yards, and room for future expansion.
Powered Shells, a Faster Path
A powered shell is an existing building with electrical service heavy enough to support data center use. The term covers shells built for data center tenants. It also describes a less obvious opportunity: older buildings that already draw significant power.
Former manufacturing plants, printing facilities, cold storage warehouses, and telecom switching buildings were often designed around heavy electrical loads. Some retain substantial service, transformer capacity, or proximity to a substation long after their original use has ended.
For an edge or enterprise operator, reusing that infrastructure can shorten the path to operation considerably. These users need far less power than a hyperscale campus and value proximity to the customers and networks they serve. In land-constrained markets such as Miami-Dade and Broward, reuse is often the more practical path.
Signs a Building May Qualify
Not every older industrial building can support a data center, and many cannot. Owners can, however, look for several indicators before seeking a formal assessment:
Heavy existing electrical service. Service sized for manufacturing, refrigeration, or printing equipment rather than ordinary office or warehouse use.
Proximity to a substation. A short distance to utility infrastructure can reduce both the cost and the time of any upgrade.
Redundant power feeds. A second utility feed, or room to add one, supports the reliability data center users require.
Structural capacity. Floor loads and clear heights able to carry server racks, cooling equipment, and raised floors.
Fiber access. Nearby fiber routes, ideally from more than one carrier.
Site room. Space for generators, cooling equipment, fuel storage, and a security perimeter.
Compatible zoning. Zoning that permits data center use, or a realistic path to approval.
How Data Center Sites Are Priced
Data center buyers underwrite differently from conventional industrial or land buyers. Their pricing typically turns on six factors:
Confirmed utility capacity. The power the utility will commit in writing, not the capacity a building appears to have.
Energization timeline. How soon that power can be delivered and put to use.
Expansion potential. Whether additional capacity can be secured as the user grows.
Connectivity. Fiber routes, carrier diversity, and latency to population centers.
Entitlements. Zoning, site plan approval, and any conditions on noise, generators, or water use.
Site characteristics. Acreage, configuration, access, flood exposure, and environmental condition.
Because these factors differ so sharply from conventional criteria, the same property can carry two very different prices. Which one applies depends on whether a data center use is realistic.
What Owners Should Consider First
Is the power confirmed, or only apparent? Existing electrical service is not the same as available capacity. A utility may reallocate power a building no longer uses, and any increase requires a utility study. Capacity should be confirmed in writing by the utility and reviewed by the buyer's engineers before it is relied on in pricing.
Will local approvals support the use? Many jurisdictions now regulate data centers directly, along with generator emissions, cooling noise, and water use. Under SB 484, Florida counties and cities keep the authority to deny projects, so zoning deserves early attention.
Is timing working for or against the owner? Utility capacity is finite, and a commitment available today may be allocated to another user tomorrow. Owners who understand their property's power profile early can weigh data center and conventional buyers on equal terms before an investment sales process begins.
Megawatts, Where Value Begins
Data center real estate rewards owners who look beyond square footage. A vacant parcel near a substation, or an older building with heavy electrical service, may hold value that conventional pricing overlooks. That value is realized only once power, zoning, and timing are confirmed.
